Cholesterol Tests

• Total cholesterol
• Triglycerides
• HDL
• LDL

Who Is at Risk of High Cholesterol?

Cholesterol testing is very important if you:

• Have a family history of high cholesterol or heart disease
• Are overweight or obese
• Drink alcohol frequently
• Smoke cigarettes
• Lead an inactive lifestyle
• Have diabetes, kidney disease, polycystic ovary syndrome, or an underactive thyroid gland

All of these things can increase your risk of developing high cholesterol.

What Does a Cholesterol Test Measure?

A complete cholesterol test measures four types of lipids, or fats, in your blood:

• Total cholesterol: This is the total amount of cholesterol in your blood.
• Low-density lipoprotein (LDL) cholesterol: This is referred to as “bad” cholesterol. Too much of it raises your risk of heart attack, stroke, and atherosclerosis.
• High-density lipoprotein (HDL) cholesterol: This is referred to as “good” cholesterol because it helps remove LDL cholesterol from your blood.
• Triglycerides: When you eat, your body converts the calories it doesn’t need into triglycerides, which are stored in your fat cells. People who are overweight, diabetic, eat too many sweets, or drink too much alcohol can have high triglyceride levels.
